Details

Anti Reverse Cap Analog (ARCA) is a chemically modified cap analogue that is incorporated into mRNA through co-transcription to ensure that the 5' end of the mRNA forms the correct cap structure, which is a necessary condition for ribosome recognition and translation initiation. Its molecular formula is 3'-OMe-m7G(5')ppp(5')G.


Applications

Significantly enhance the translation efficiency of mRNA.

It can resist degradation by nucleases, prolong the half-life and stability of mRNA within the cell, thereby increasing the protein expression level. ARCA prevents the reverse insertion of the cap structure through chemical modification, ensuring maximum translation efficiency.


Features and Benefits

  • High capping efficiency
  • Minimized GTP competition
  • Improved translation efficiency
  • Resistance to decapping enzymes
  • Compatibility with delivery systems
  • Scalable one-post synthesis and cost-effectiveness
